In many cases, the container is attached to the mouth of the container body containing the squeezable plastic: the portion is detachably attached to the cover having the discharge port for use. The squeezing container is formed by, for example, detaching the cover from the discharge port, and then squeezing or tilting the held squeezing container so that the discharge σ is directed toward the discharge position, thereby squeezing the container body. The content liquid is ejected in a specific amount. Further, when the squeeze container is released from the squeeze state, the deformation of the container body is restored, and the inside becomes a negative pressure, and the liquid is sucked by the so-called back suction effect, whereby the content liquid around the discharge port can be sucked back to the container body. internal. On the other hand, when the pressure-adjusting container is held by the crotch portion of the container body so as to be tilted or inverted, the content liquid may leak or drip from the discharge port due to the internal pressure of the container body and the weight of the content liquid. Such unintended content or dripping becomes a cause of contamination of the appearance of the contaminated squeeze container or the use of it, so the industry has developed various techniques to prevent such conditions (for example, a, g straight, seven sides, Patent Document 1: ',,, Patent Document 1, Patent Document 2, and Patent Document 3). In the case of the patent document 1, in the patent document 1, in the patent document 1, in the patent document 1, in Japanese Patent Laid-Open Publication No. JP-A-2006-219181 A cover for the discharge port is formed in the center of the top surface portion, and a side wall extending obliquely from the peripheral edge portion of the top surface portion toward the center side is formed, thereby preventing the liquid leaked before the pressing from adhering to the periphery of the container body. However, since the top surface on the inner side of the peripheral portion leaks liquid over a wide range, the back suction by the sucking liquid is not sufficient, and the liquid cut becomes poor. On the other hand, in Patent Document 2, the dip tube that communicates with the discharge port of the cap is 1; the shape is curved, and the liquid inflow port is disposed near the discharge port. Thus, as long as the container body is not squeezed, the content liquid is not self-contained. The squirting of the σ is effective to avoid the generation of excess droplets. However, *, presented! The tube-shaped curved tube structure has a case where the operation of attaching and detaching the lid becomes inconvenient, and if the content liquid is squeezed in a state in which the content liquid remains inside the dip tube, there is a generation of air mixed with the liquid. The situation of scattering around. On the other hand, in Patent Document 3, a bottomed cylindrical collecting groove (Trap r_) is fixedly disposed on the lower side of the discharge port, and a communication hole is formed in the peripheral wall portion and the bottom portion of the bottomed cylindrical body, thereby allowing the residue. The liquid in the collection tank is returned to the container to avoid droplets. However, if the collection (4) does not accumulate - (four) degrees (4), the corpus callosum cannot be discharged, so in particular, problems arise in that the first discharge amount is small or cannot be adjusted. Therefore, in any case, the stabilization of the amount of W, the prevention of droplets, and the good liquid cutting are not sufficiently satisfied, and development of a technique capable of preventing the above problems is expected. The invention relates to a cover for a squeeze container, which can effectively avoid leakage or dripping of the crushed liquid of the 151314.doc 201118019, and can obtain a good liquid cut by suckback, and has an easy cover. The compact shape of the operation during loading and unloading, and also effectively avoids the incorporation of air into the content liquid. The present invention provides a cover for a squeezing container which is mounted on a 包含 Μ portion including a squeezable deformable body, and which is made by extrusion deformation of the crotch portion of the container body The liquid is ejected from the discharge port at the front end. Further, the present invention provides a cover for a squeeze container which is configured to divide at least a portion of a liquid flow path from the neck portion of the container body to the discharge port into a spiral flow path.

Further, the container body 12 can be formed using various known synthetic resins, and is easily formed by, for example, blow molding. 151314.doc 201118019 Further, as the content liquid which can be accommodated in the container main body 12, the liquid composition for measurement 2 includes, for example, a liquid detergent for clothing, a softener, a bleaching agent, a liquid body wash, and the like. In addition, it can also be used in liquid foods for cooking oil and seasonings. The lid 10 for squeezing a singularity is, for example, a plastic molded article, and includes a circular top surface portion (10) and a peripheral wall portion 10b extending from the peripheral portion of the shell portion 10a downwardly. The top surface portion 1A is provided with a nozzle portion 19 from a central portion thereof. The nozzle portion 19 includes a cylindrical intermediate portion 19b that is erected from the top of the top surface, and a nozzle body 19a that is fixed to the front end portion of the cylindrical intermediate portion 19b. The cylindrical intermediate portion (10) of the nozzle portion 19 and the center of the nozzle body are penetrated in the vertical direction to form a discharge port 13. Further, in the nozzle portion 19, the lid body 16 which is openably and closably covered at the front end of the nozzle body is rotatably joined to the nozzle body 19a via the hinge portion 17, and the discharge port 13 can be sealed when the squeeze container U is stored. . The circumferential wall portion 1 〇b of the rounded skirt shape is provided with an internal thread on the inner side surface of, for example, the substantially lower half portion, and is fastened to the neck portion I2a$ & m T of the container body 12 by, for example, An external thread is provided on the outer peripheral surface, and the cover 1 is detachably attached to the neck portion 12a. In the first embodiment, the spiral cylinder 14 disposed inside the lid 1 of the squeeze container and forming the spiral flow path 15 is made of a plastic product, and is formed in the following state as shown in (4) and (9). 'The cylindrical side of the hollow circular cross section is wound and the surface is stretched in a coil spring-like spiral shape. Further, the upper end portion is bent inward in the radial direction, and is further bent upward along the central axis portion of the spiral shape, so that the upper end mounting portions 14c of the two locking bottom lines 151314.doc 201118019 are provided to stand up. The upper end opening w is open upward. Further, the spiral cylinder 14 is formed in a state in which the lower end opening l4b is opened obliquely downward in the tangential direction of the spiral shape. Further, in the first embodiment, the upper end mounting portion mc' of the spiral cylinder 14 is attached so as to repeatedly enter the lower end portion of the cylindrical intermediate portion m of the nozzle portion 19, whereby the spiral cylinder 14 is self-tubular The state in which the lower end portion of the intermediate portion (10) is suspended is disposed inside the peripheral wall portion i〇b of the cover 10. Also, by this, the spiral barrel! The upper end portion of the fourth portion is open to the discharge port via the upper end opening, and the lower end opening (10) of the lower end portion of the spiral barrel 14 is opened to the inside of the neck portion 12c of the container body 12 and is spirally bent by the spiral barrel 14. The bottom surface portion 15a of the extended spiral flow path 15 is formed so as to be inclined downward from the upper end portion of the spiral cylinder 14 toward the container body with the continuous inclination of the month portion 12b in a state where the pressing container u is erected. Further, according to the lid 10 for a squeeze container of the present embodiment having the above-described configuration, leakage or dripping of the content liquid before the squeeze container u can be effectively prevented, and the back sucking effect can be obtained well. The liquid is cut and has a compact shape which is easy to handle when the cover 10 is attached and detached, and the air of the content liquid can be effectively prevented from entering. In other words, according to the lid for the squeeze container according to the first embodiment, the spiral flow path 15 is formed by bending and extending at least a part of the liquid flow path from the neck portion 12a of the container body 12 to the discharge port 13. When the squeezing container 11 is tilted or inverted, the inner sump liquid is bent and extended by the spiral flow path 15 and then ejected from the sputum outlet 13 after the squeezing container 11 is tilted or inverted. Therefore, the 'content liquid can be smoothly passed through the liquid flow path from the outlet port ^ 151314.doc 201118019 ^ and the inner valley liquid is required to pass through the curved spiral flow path 5 for a long time. Further, during the period in which the content liquid is ejected, that is, during the passage of the content liquid through the liquid flow path, since the content liquid and the wall surface of the spiral flow path 15 are integral (4), it is difficult to replace the air into the flow path from the outlet 13 and the length can be long. When... stay in the content liquid. Thereby, the squeezing container u is inclined or inverted so that the discharge port η is directed toward the discharge point until the 胴 (3) of the squeezing container (4) is _ ', which can effectively prevent the internal pressure of the content liquid due to the container body 12 And the weight of the inner trough liquid leaks or drops from the discharge port 13. According to the first embodiment, as described above, it is possible to effectively prevent leakage or dripping of the content liquid before the chest is immersed. Therefore, it is possible to obtain a good liquid cut by desorbing the content liquid in the squeezing state 2 . Such a sucking liquid cut can be obtained by a method which obtains a better liquid cutting effect, that is, the volume of the liquid flow path (spiral flow path 15) which is extended by the spiral tube 14 is smaller than that of the squeeze The volume reduction of the portion 12b of the container body 12 when the pressure is pressed into the HU is pressed. Further, according to the cover 挤压 for the squeeze container according to the first embodiment, the spiral tube 14 which forms the spiral flow path is housed inside the peripheral wall portion (10). The compact shape is detachable from the neck portion i2a of the container body 12 by substantially the same operation as the previous cover. Furthermore, according to the cover 1 for the extrusion container according to the present embodiment, the bottom surface portion of the spiral flow path which is bent and extended by the spiral leopard 4 is in an upright state of the pressure container 1 The hole portion m of the container body 12 is inclined downward. Therefore, if the squeeze container is placed in an upright state after use, for example, even if the content liquid remains in the spiral flow path 15, the 151314.doc 201118019 remains. The content liquid can also be inclined downward along the bottom surface portion 15a, and flows down by its own weight, thereby smoothly recovering into the crotch portion 12b of the container body 12. Therefore, when the squeezing portion 12b of the container body 12 is gripped when the squeezing container 下次 is used next time, the spiral flow path 15 which is bent and extended does not remain in the state of the liquid, so that it can be effectively Avoid scattering of the content liquid due to the incorporation of air into the content liquid. Further, in the first embodiment, since it is not necessary to reduce the cross-sectional area of the discharge port 13 or the liquid flow path, it is possible to effectively prevent the increase in the pressing pressure when the crotch portion 12b of the container body 12 is squeezed. The liquid flow path in the lid 20 of the squeeze capacity is shown in Figs. 3 and 4 as a cover 20 for a preferred second embodiment of the present invention. In the squeeze container according to the second embodiment, the spiral flow path 15 constituting at least a part from the neck portion 12a of the container body 12 to the discharge port 13 is provided at the discharge port 13 facing the cover 2 The cylindrical blade 21 is formed in a cylindrical shape on the lead path 18. That is, as shown in Fig. 5, the spiral blade 21 is a plastic molded article integrally formed on the center shaft member 22. The spiral blade 21 is disposed so as to be joined to the peripheral edge portion of the opening of the lower end of the cylindrical lead-out passage 18 by, for example, a support rod 23 integrally provided at the lower end portion of the center shaft member 22, preferably the peripheral end surface of the spiral blade 21 is The inner peripheral surface of the cylindrical lead-out path 18 is pressed into the upper portion of the diminutuous lead-out path 18. By the spiral blade 21 disposed on the cylindrical lead-out path, the curved flow is formed on the liquid flow path from the neck portion 12a of the container body 12 through the cylindrical lead-out path 26 to the discharge port of the cover 25! The spiral flow path 15. X, the bottom surface portion 15a of the spiral flow path 15 provided by the spiral blade 21 is formed in the upright state of the squeeze container u, and is formed from the upper end of the spiral blade 151314.doc 201118019 piece 21 The crotch portion 1 2b of the container body 12 is inclined downwardly and continuously inclined. Further, according to the cover 2 for the extrusion container according to the second embodiment, the spiral flow path 15 which is bent and extended by the spiral blade 21 is provided. From the neck portion 12a of the container body 12 to the discharge port 13, at least one portion of the liquid flow path is formed, and the bottom surface portion of the spiral flow path 5 formed by the spiral blade 2 is formed in the squeeze container 11 Since it is inclined downward in the upright state, the same effects as those of the lid for the squeeze container according to the first embodiment described above can be achieved. Further, the present invention is not limited to the above embodiments, and various types of text can be performed. For example, to form from the body of the container The member of the spiral flow path provided on at least a part of the liquid flow path from the neck to the discharge port is not limited to the above-mentioned spiral cylinder or spiral blade, and various other members may be used. The U may also be toward the top of the cover. A mounting plate or the like in which a spiral groove is formed on the inner side of the face. [Industrial Applicability] According to the cover for a squeeze container of the present invention, leakage of the content liquid before the squeeze container is effectively prevented Or dripping 'and can obtain a good file by sucking back' and has a compact shape that is easy to handle when the cover is unraveled' and can also effectively avoid air incorporation into the content liquid.
